Since the days of the Apollo missions in the 1960s, the wake-up song has been a part of the space program. Astronauts have been awakened from their space slumber by songs that they chose or that their families picked. But now NASA is allowing the public to vote on songs that will act as alarm clocks on Endeavor’s last mission before it is retired.

NASA said the two songs with the most votes will be announced and played for two days during the 14-day mission, which is slated to launch April 19. Voting will be open until the day of launch.

The space agency allowed the public to vote on a wake-up song during Discovery's last mission. On March 8, astronauts were awakened with a live performance from Houston's mission control of "Blue Sky" by Big Head Todd and the Monsters. Watch the video here.
